Got a question. Do I have to grind on the cam to clear a 5.75 stroke crank on a 300 block? Or would a 350 block be better? I don't think it will matter between blocks but just wanna make sure. Or would a 5.5 stroke be better without having to grind clearance on the came?
 
What rods are you using? If you"re using stock rods you need to clearance the cam already at 5.25"
 
I'm mainly looking for what I need to get to run a 5.75 stroke crank. Hopefully without clearancing the cam. Or if I need to go with a 5.5 stroke. Thanks for some info.
 
I'm just trying to figure out if I need tovgring my cam for clearance if I got with a 5.5 it 5.75 stroke. If I use aftermarket rods. I've been looking at murpheys. I just need to know what to stroke my crank to.
 
Call and talk to Jeff at Murphys. I'm pretty sure he's got a stroker kit available for the H-350 series engine with the crank/rods/pistons and cam. He can tell you what you'll need for a particular stroke.

cutting the cam and notching the bottoms of the bores using stock H rods. wouldnt do it any other way unless your having it built by someone who cant do it.
 
OK thanks. If I pull the sleeves out of a 350 block hat sizes pistons do u recommend running? And in a 300 block can you pull the sleeves and put a oversize bore 350 sleeve?
 
AWchevy, Can't help on piston size to use, I'm not that familar with the H-350 engines. I'm close to Murphy's shop and stop in there every now and then, so I have some knowledge of what he's got going on there. Good luck with your project. Mike
 
If you are pulling the sleeves out of a 350 or 300 block 3.8125" is the bore size to use unless you are going to hard block it. How much do you want to spend? If you want 5.75" stroke call Murphys he will set you up for less money in one stop than you will spend trying to piece it together yourself.
 
Not sure how far you can go with hardblock, I have not tried it yet. Gary Baker could point you in the right direction there. Also Jeff down at Murphys will have more insight than me.
